管道配置文件为YAML格式,放置于PIPELINE_DIR目录下,示例:
yaml# example-pipeline.yaml name: "user-data-transform" description: "转换用户数据格式并输出至API" steps: - name: "input" type: "http" config: url: "[***]" method: "GET" - name: "filter-active-users" type: "filter" input: "input" config: condition: "$.status == 'active'" - name: "transform-format" type: "transform" input: "filter-active-users" config: mapping: user_id: "$.id" username: "$.name" *** "$.contact.email" join_date: "$.created_at | strftime('%Y-%m-%d')" - name: "output" type: "http" input: "transform-format" config: url: "[***]" method: "POST" headers: Content-Type: "application/json"
